Buyers are being misled by stories highlighting GNI's 15% dividend yield, but GNI is a royalty trust that, according to its own website, will terminate - worthless - on April 5, 2015; only five quarterly dividends plus a final distribution will be paid prior to termination, the author writes.

Remaining distributions will total ~$21; "it certainly doesn't make sense to pay any more than that," Night Heron says, yet shares are selling for $67.
